That is the fastest way. Note that the first tab is just to get rid of the IntelliSense tooltip. The second tab is the one that actually does the work. In other words, you can do cw + esc/tab/enter + tab or even c + esc + w + tab. Or you can even type cw, go somewhere else, click right after the cw then tab and it will auto complete.

That could be annoying if you do something like var cwtab.

Edit: Once you have used "cw", you can then do it a bit faster by just typing c + tab + tab. Since you last used "cw", the c will select "cw" from IntelliSense, the first tab will insert it, and the second tab will auto complete.
